In the embodiment shown, the apparatus is illustrated as having an upperframe memher 1 which is suitably mounted upon a lower frame member 2.Preferably, but not.

of necessity, there is attached to the upper frame 1 a pair of brackets3 which are rigidly mounted in a suitable manner in order to support acard provin box generally denoted by the number 4.

11 Figs. 4, 6 and 7, there are shown sectional views of the provin boxillustrating the improved details t ereof', and in these views it willbe noted that the brackets 3 are integral with one another beingconnected by the perforated plate 5 which forms the top of the provingbox, and has a forward extension 6 which curves downwardly at its frontend .7. The brackets on their opposing faces just below the perforatedplate 5 are each provided with a substantially semi-circular flange 8terminating at each of its ends at the plate 5. A metal housing 9 issecured to these two flanges 8 forming a trough-shaped construction asshown. Between the upwardly extending ends of each of the flanges 8there is provided a straight flange 10 extending across the side of thebracket, and by means of these flanges 10 there is supported a glassplate 11 composed of either clear or ground glass. Inside of the boxjust described and secured to each of the sides of the brackets 3 thereis provided a lamp 12 of the usual electric incandescent type. At theupper end of the rear end of each of the flanges 8 there is provided arear extension 13 to which there is secured a slotted plate 14, theslots of which are in alinement with the rows of perforations in theplate 5.- At the upper end of the front end of each of the flanges 8there is provided a similar slotted plate 15 Whose slots are also inalinement with the perforations in the plate 5 and thus also with theslots of the plate 14. Thus there is formed between the glass plate 11and the perforated plate 5 a chamber 17.

The card to be proved is positioned on top of the perforated plate 5,this card being illustrated in Fig. 3 as C and being of the usual typehaving a plurality of rows of numerals printed thereon, each row containing twelve figures, viz: 12, 11, 10 and 1 to 9 inclusive, as clearlyindicated in the third column marked 47. Data is indicated on this cardby perforating the portion of the card at the proper position in a rowwhich perforation will appear instead of the numeral as indicated inFig. 3 by the black dots 16. The perforations in the plate 5 correspondto the figure spaces of the several rows of the card C. Thus when any ofthe perforations in the plate 5 are blocked by some suitable meanslocated in the chamber. 17, this blocked perforation corresponds to theperforation in the card, and thereupon the lamps 12 in the proving boxare illuminated, no light will shine through such perforation in thecard C, whereas if the blocking means did not register with theperforation in the card C, the light from the lamps would appear andthereby indicate that the card being proved was wrongly perforated.

The means for receiving and holding the card on the plate 5 comprisestwo guides 18, 18 (Figs; 6 and 16) which guides are secured to the topof the plate 5' by any suitable means preferably being spaced from theentrance side E of the plate 5 and adjacent to the exit side X of theplate 5, and extending transversely of the rows of numerals. Each of theguides has a groove 19 formed in it adjacent to the plate 5 which grooveflares outwardly at the entrance end of said guides 18 as shown at 20.The cards are fed into and located in these grooves 19 when in provingposition, the flaring portions 20 directing the card to proper positionwhen being fed into said grooves 19. At the entrance end of the plate 5,there is located a hook portion 21 comprising a plate bent back uponitself. At the exit end of the plate 5 there ispositioned a limitingplate or stop plate 22 which is fixed to a shaft 23 journaled in thebearings 24 which, in the present instance, are integral with and extendup from the ends of the guides 18. The shaft 23 has mounted thereon aspring 25 fixed to one of the bearings 24 and the body of the shaft 23tending to maintain the shaft in such a position that the stop plate 22secured thereto will have its lower end bearing against the inner end ofthe recess 26 formed at the exit end of the plate 5. From the foregoingit will be seen that when the card is fed in from the entrance end ofthe plate 5, the card will pass over the hook 21 and be directed in thegrooves 19 by means of the flaring portions 20 and strike against thestop plate 22 at the exit end of the plate 5. Upon striking the stopplate 22, the card will be released and the stop plate 22 by means ofits spring tension will thrust back the card C and feed it into the hook21 whereby the card will be positioned. When it is desired to dischargethe card, it is only necessary to feed the same forward against the stopplate 22 (Fig. 9) and the card C will pass under said stop plate 22 andout from the plate 5.

Means for blocking the perforations in the plate 5 comprise slide barseach embracing two sections one series of sections being permanentlyconnected with the provin'g box, and the other series of sections beingpermanently connected with the frame 1. The series of sections or slidebars permanently connected with the proving box are designated as 27 andare slidably mounted in the slots of the plates 14 and 15, such plates14 and 15 supporting the sections 27. At the lower rear end of each ofthe sections 27 there is formed a notch 28 producing the hook portion29. On the upper edge of each of these sections 27 there is formed ablocking member 30 preferably comprising a pad composed of a suitablesubstance such as felt. These blocking members 30 are positioned on thesections 27 between the members 14 and 15 and block any one of theperforations in the row under which the section 27 slides according tothe position of the section 27.

The sections 27 connect with the series of sections or slide bars 31permanently connected with the main frame 1 by means of the hook portion29 engaging in the recess 32 of the several sections 31 respectively.such sections 31 each having a guiding slot 33 at its front end providedwith a lower inclined surface, sothatthe hook member 29 of a section 27will engage in arecess 32 and the inclined surface of the slot 33 andthe sides of such slot 33 Will-lck the section 27 against displacement.

The sections 31 are provided with trans-1 versely extending openings 34all in alinement with one another and each of a width practically theentire length of a section 31 through which inclined openings 34 thereextends a guide plate 35 secured to the main frame}, whereby thesections 31 will be slidably mounted and yet locked to the main frame 1.

Each of the sections 31 is provided at its rear end with a socket member36 to" be en gaged by one of the series of levers 37, in the presentinstance, these levers being pivoted on a common shaft 38 and eachhaving a lower arm 39 rounded at its end to engage in a socket member36. Each of the levers 37 is also provided with] an upper arm 40similarly rounded at its end to engage in one of a series of socketmembers 41 respectively, each of which socket members 41 is connected toa key slide 42.

There are a plurality of these key slides 42 one for each row of a cardand having graduations thereon to correspond with the figures 12, 11, 10and 1 to 9 inclusive, of a row in a car The key slides 42 are mounted toslide on the top of the frame and are so mounted and held in position bymeans of metal strips 43 spaced apart from one another and extendingfrom the upper extension 44 to the lower extension 45 of the frame 1 andhaving their ends fastened to such extensions 44 and 45. The key slidesare mounted to travel between such strips 43 and are each-provided withgrooves 46in their sides into which the strips 43 extend and therebyconfine the key slides to a sliding movement.

Fastened to the lower extension 45 of the frame 1 and extending up fromthe strips 43 for a certain distance, there is secured a plate 48 onwhich the hands of the operator may rest while manipulating the keyslides 43. The key slides are each provided with a series oftransversely extending notches 49 on their upper surface, of which thereare twelve corresponding to the number of figures in a row of the cardC, and are also each provided on their lower surfaces with a like numberof notches 50. The notches 49 are numbered 12, 11, 10 and 1 to 9inclusive, similarly to the rows of a card, and when the finger isintroduced into any one of the notches 49 of a key slide 43 and such keyslide moved forward until the finger touches the plate 48, the lever 37connected to such key slide 49 will by said movement slide the theretoconnected sections 31and 27 to move a pad or blocking member 30 underthe corresponding perforation'in the plate 5.

The levers 37 are each provided with a spring 51 connecting their lowerarms 39:

to the lowerextension 45 of the main frame whereby such levers 37 arenormally main-- tained in a position where they hold the key slides ininitial or uppermost position and likewise return such key-slides 42 tosuchuppermost position when the key slides are released. To lock themoved key slides 42 in their advanced or lower positions, there areprovided a plurality of ratchets 52 pivoted on a common shaft 53 fixedto the main frame 1 below the plate 48. Each of these ratchets 52 isprovided with a tooth 54 extending upwardly from its rear end to engagein the notches 50, the frontend of which ratchets isconnected by aspring 55 to the cross bar 56 whereby the rear end of the ratchet isnormally maintained in raised or notch engaging position. Forindividually releasing any one of the ratchets 52, a plurality of levers57 are provided loosely mounted on the common shaft 58, their rear endseach contacting with the lower surface of 'the front arm of a ratchet52, and their front arms projecting through an opening 59 formed in theextension 45 belowvthe plate 48 in'which position the operator caneasily depress any one of the levers'that may be desired.

For releasing all of the ratchets simultaneously which may be desiredwhen resetting the machine for proving the next succeeding card, theratchets are each provided with a downwardly extending portion 60 havinga forwardly extending tooth 61. Forwardly of these downward extensions60 there is located a shaft 62 to which there is fixed a plate 63'having its rear end extending over and onto the teeth 61, thus when therear end of plate 63 is depressed, it will therewith depress the rearends of the ratchets 52 and simultaneously release all of the ratchets.For so depressing such rear end of the plate 63, theplate 63 is providedwith an extension 64 to the rear end of which there is pivoted a link 65the lower end of which is pivotally connected to a treadle 66 pivotallyconnected to the lower frame 2 so that the depression of the treadle 66will in turn depress the rear end of the plate 63 to release theratchets 52.

On the treadle is arranged the means whereby the illumination of thelamps can be effected. The foot-rest of the treadle is preferably aplate 67 having a plurality of openings 68. Through one of theseopenings preferably through one at the side of the plate, in the presentinstance, shown at the upper end of the rightside of such plate 67, abutton 69 rojects which is fixed at the end of a lever 70 secured to ashaft 71 on which a drum/72 is fastened, the shaft 71 being journaled ina housing 73 secured tothe lower side of said plate 67 and the drum 72being positioned in said housing. .On one side of said drum 72 there isfixed an elec trio contact plate 74, the drum itself being composed of asuitable insulating material. Fixed in one side of the housing 7 3 andextending therethrough are two pins 75, 75 suitably insulated from thehousing, having asoreW-threaded connection with said housing, and aknurled nut 76 on each of said pins positioned outside of said housing.The pins extend into said housing and form contactpoints to be engagedby said contact plate 74. The drum 72 is normally positioned so that itscontact plate 74 is out of contact with the pin 75, thus breaking thecircuit, the drum being held in such normal position by a spring 77fastened at one end to the shaft 71. which extends out of said housingand at its other end to the housing 73. By depressing the button 69 andthereby depressing the lever 70 to rotate the drum 72, the plate 74 atthe depressed position of said lever 7 0 will be moved into positionwhere it contacts with the pins 75. The pins 75 form the binding postsfor the electric wires 78 (Fig. 2) which properly connect the lamps 12with a source of electric power such as the battery 79 when the plate 74is in contact with the pins 75 The foregoing arrangement is such thatwhen a card is properly positioned in the proving box 4 and the pads 30properly set for a reading, the operator will move his foot over to thebutton 69 and depress the same, whereby the pins 75 and plate 74 will bemoved into contact with one another to connect the battery with thelamps 12 and thereby illuminate the same. Upon such illuminations, thelight will shine through any uncovered perforation and thus it may beseen whether the card has been properly perforated.

After the lamps have been illuminated,

' and the reading made, the pads 30 and key slides 42 may thereupon bereset for the next succeeding card which is done by depressing thetreadle 66 itself, whereby the plate 63 will be depressed to release theratchets 52 which in turn as already described will permit the keyslides 42 and pads 30 to be returned to initial position by means of thelevers 37 After the foot of the operator has depressed the button 69,and it is desired to depress the treadle itself,

the operator may either shift his foot from the button 69 to extinguishthe lamps before depressing the treadle or else depress the treadlewithout shifting his foot from the button and thus effect therestoration of the pads 30 while the lamps are illuminated.

In order to permit gang setting of the key slides 42, whereby data whichis common to a number of cards to be proved, need not be reset for eachseparate card, I have provided a gang locking plate 80 having a numberof punched-out fingers 81 corresponding to the number of notches 49 onthe key slides 42. At the front of the locking plate 80 there isprovided a handle member 82 which is fastened to the plate 80 and has alower extension 83 provided with a fixed washer 84 at its lower end anda movable washer 85 at its upper end between which washers there isstrained a spring 86. The washer 85 is of greater diameter than the"space between the strips 43, the lower end of the handle member 82being disposed on the upper surface of the looking plate 80 and thewasher 85 on the lower surface of adjacent strips 43, the spring 86serving to clamp the strips 43 between the locking plate 80 and thewasher 85. On the frame member 44 there is provided a transverselyextending bar 87 of a thickness that is sufiiciently small to permit thefingers 81 to engage around it. In the operation of this gang lockingplate 80, the handle 82 is grasped and moved down to the notch in thekeyboard corresponding to the data which is common to a number of cardsto be proved, and thereby a corresponding finger 81 is engaged on thetransversely extending bar 87, the handle member 82 released and thespring 86 permitted to clamp the looking plate in place. By this means,whenever the key slides are released to return to normal position, thosekey slides which have locking plates set in their path of movement arelocked against being returned to normalposition'and thus ready for thenext card to be proved without an independently. and separate setting ofsuch common data.
